Watching the spiraling price of gold (the spot price as of this writing is $1,213.40/oz) has been a humbling experience for me. There are all kinds of marketing forces happening to cause this, but if you follow what the Austrian School folks are saying, this is not a surprising trend at all. Central banks around the world are dumping their U.S. dollars and buying up gold, which is driving the price up. But I think this is different than just another commodity bubble, because the way gold is perceived--as a store of wealth. Traditionally investors who feel the currency they are in is threatened ...

A DefineSound tag declares a set of samples of a sound effect or a music.

The sound samples can be compressed or not, stereo or not and 8 or 16 bits. The different modes are not all available in version 2, although the same tag is used in newer versions with additional capabilities.

The f_sound_is_16bits is always set to 1 (16bits samples) if the samples are compressed (neither Rawnor Uncompressed).

The f_sound_rate represents the rate at which the samples are defined. The rate at which it will be played on the target computers may differ. The following equation can be used to determine the ...

	unsigned char		f_font_info_name[f_name_length];

		unsigned		f_font_info_small_text : 1;
		unsigned		f_font_info_reserved : 2;
	}

	if(version >= 6 && f_tag.f_tag == DefineFontInfo2) {
		unsigned char		f_font_info_language;
	}
	if(f_font_info_wide) {

	}
	else {
		unsigned char		f_font_info_map[f_font_glyphs_count];
	}
};

A DefineFontInfo tag will be used to complete the definition of a DefineFont tag. It uses the exact same identifier (f_font_info_id_ref = f_font_id). You must have the corresponding font definition appearing before the DefineFontInfo since it will use the number of glyphs defined in the DefineFont to know the size of the map definition in the DefineFontInfo tag.

When it looks like it perfectly matches an existing system font, the plugin may use that system font (as long as no rotation is used, it will work fine.) It is also possible to force the use of the system font by declaring an empty ...

struct swf_definefont {
	swf_tag			f_tag;		/* 10 */
	unsigned short		f_font_id;
	/* there is always at least one glyph */
	f_font_glyphs_count = f_font_offsets[0] / 2;
	unsigned short		f_font_offsets[f_font_glyphs_count];
	swf_shape		f_font_shapes[f_font_glyphs_count];
};

It is common to use the DefineFont tag in order to create an array of shapes later re-used to draw strings of text on the screen. Note that the definition of the shape within a font is limited since it can't include any specific fill and/or line style. Also, each shape is assumed to be defined within a 1024x1024 square. This square is called the EM Square. Fig 1. below shows you the EM Square and how it is used. The characters baseline can be placed anywhere within the EM Square (it certainly can be outside too if you wish?!?).

Brief History

At the very beginning, a company created the SWF format to generate small vector animations on the Internet called Shockwave Flash (hence the name of the format, SWF.) It also included images. This company was bought by Macromedia around 1997 (if I recall properly). This is when Flash v3 was created. Since then, Macromedia created a new version about once a year up to version 8. At that time (in 2005/2006), Macromedia sealed a deal with Adobe which wanted to use the SWF format in their PDF files.

Today (May 1st, 2008), the SWF format is available for free to all.

We have been running Drupal for some time now and we have noticed that it generates a very large amount of warnings in our log files.

The warning is in link with improperly formatted strings. PostgreSQL tries to follow the SQL specification to the letter and that means you cannot use the backslash character to escape special character sequences (such as \n for a newline character.)

I knew that in most cases the error was generated because of the function saving a full page or some other content in the cache. In that case, the system includes the characters: \012 and \015 (\n and \r.) That ...

They are using a Web 2.0 system with PHP running on their server along Apache version 2.x. In other words, they most certainly are running Linux as their server operating system.

It happens that a column in your main display look too wide. Say you use three columns, one may be real large and two are the normal size (1/3^rd of the screen.)

In general this happens because you have a URL in one of your description. (If the URL is in the title, I strongly advice that you move it to the description.) Then the description shows up as wide as that URL. Long URLs will have a real bad effect making the column much wider.

There are two ways to solve the problem:

1. Create a tiny URL, although tiny URLs may still be too big, it may help
2. Change the settings of the ...
